Issue222832

A minor difference between CPython and JPython. When imported, 
sys.__dict__ is None in JPython.


[d:\]jpython
JPython 1.1beta4 on java1.2.1 (JIT: symcjit)

>>> import sys
>>> sys.__dict__['platform']
Traceback (innermost last):
  File "<console>", line 1, in ?
AttributeError: __getitem__
>>> print sys.__dict__
None
>>>


[d:\]python
Python 1.5.2 (#0, Apr 13 1999, 10:51:12) [MSC 32 bit (Intel)] on win32
Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
>>> import sys
>>> sys.__dict__['platform']
'win32'

Fixed by copying the class attribute to the __dict__.
